马兰(Kalimeris indica)通常用根茎繁殖,但费工,用种子繁殖出芽率达98％,在5℃左右即萌发。用茎分段扦擂也易成活,但叶插尚不能成活。河坡种马兰宜丛植,勤拔草。马兰在上海可全年种植,年亩产可达4000kg,低畦平畦产量比高畦好,马兰收获最盛期是3～6月及10月。 Kalimeris indica usually grows with rhizomes, but it takes a lot of work to seed germination rate of 98%, germination at about 5 ℃. Sectional stem beat with bees is also easy to survive, but the leaf plug still can not survive. Horseshoe blue cedar bush planting, ground pull grass. Malan planted throughout the year in Shanghai, the annual output of up to 4,000 kg per mu, low-breed flat-breed production is higher than high-breed, Malan peak harvest period is 3 to June and October.
